feat: add `sentry event list` command + `events` plural alias

[BYK]

Summary

Add a list subcommand to sentry event to list events for a project, and register events as a plural alias (like issues → issue list). This is requested by users in CLI-Q3 telemetry (~6 events trying sentry event list).

Implementation Details

API Endpoint

GET /api/0/organizations/{org}/projects/{project}/events/ (project-scoped event listing)

New API Function

Add listProjectEvents to src/lib/api/events.ts:

• Paginated response using apiRequestToRegion + parseLinkHeader
• Return type: PaginatedResponse<SentryEvent[]>
• Accept org slug, project slug, and standard pagination/query options

New Command

Create src/commands/event/list.ts:

• Register as list in src/commands/event/index.ts route map
• Accept optional [<org>/<project>] target positional (auto-detect from DSN/defaults)
• Support --limit, --cursor, --query, --json, --fields flags
• Follow existing list command patterns (org-list dispatch or standalone pagination)

Plural Alias

In src/app.ts:

• Add events: eventListCommand to the top-level routes (import listCommand from event/list.ts)
• Add events: true to hideRoute
• Add events: "event" to PLURAL_TO_SINGULAR

References

• List command patterns: src/commands/issue/list.ts, src/commands/trace/list.ts
• Event types: src/types/sentry.ts (SentryEvent)
• Plural alias pattern: see existing issues, traces, logs in src/app.ts

Context

A temporary synonym suggestion for event/list exists in src/lib/command-suggestions.ts. Remove that entry once this command is implemented.
